Geologic setting

Geologic description

This prospect occurs in greenstone that contains epidote-filled amygdules. The deposit consists of pyrite, arsenopyrite, and chalcopyrite in steeply-dipping shear zones. The principal zone is 21 feet wide and strikes N10E. The sulfides occur mostly as replacement bands of ore minerals parallel to shearing or as intergrowths of several minerals in the sheared greenstone. Minor quartz is associated with the sulfides. Sulfide disseminations also occur in greenstone lenses in the shear zone and in the country rock extending some distance from the shear zone (Capps, 1919 [B 592]). The claim owners reported samples assaying 'several dollars a ton in gold'.
